"But I'm truly blessed beyond belief, and I really don't know what we're going to do. But right now, I'm really happy being on this side helping our fighters."

Mayweather got to 49-0 with a decision over Andre Berto then officially hung his gloves up. Before that, he won by unanimous decision a lackluster match with Manny Pacquiao, who declared after the fight he was injured in training and aggravated it during the bout.

Undefeated Gennady Golovkin has been mentioned as a possible match, but Mayweather has waved off a leap to middleweight saying he cannot even make 154 lbs.
